Table 3-4.Phenomenon:
Printer Fails to Load Paper Frequently.
Step Remedy
1 Paper types available and the way to set vary depending on the
cassette types; standard cassette or optional cassette. Look into
the User’s Guide and set the paper which is not available to the
optional cassette to the standard one.
2 Check that the paper set in the cassette does not exceed the
capacity.
3 Check that the edge guides in the cassette are properly aligned
with the paper sides.
4 A separation pad in the paper cassette must be kept to have
proper friction with paper. If the user touches the pad surface, it
affects paper separation. Therefore, when this problem occurs
wipe the paper separation pad surface with a cloth moistened
with alcohol.
5
If a PF roller is used for many years, it starts losing proper
µ
due
to friction built up on its surface. In stand by status, the roller can
not be cleaned as it is facing upward. Therefore, clean the roller
in the following order when this problem occurs:
1. Remove the paper cassette.
2. Turn the printer off and back on, and the ASF resets.
3. Using the cloth moistened with alcohol, wipe the PF roller as
the roller rotates.
Table 3-5.Phenomenon:
Printer Loads Multiple Paper Frequently.
Step Remedy
1 The hopper 5-mm down mechanism may not be properly
functioning. Referring to Section 2.1.1.7 in Chapter 2, check the
mechanism in the following step.
2 Check that the spring in the clutch gear which acts to bring the
lifter down by 5 mm is properly set. To check it, hold one gear
(either inner one or outer one) and then turn the other gear
manually. If the turned gear spins back with the tension of the
spring, it means the spring is set properly.

Hopper does not Reset after Paper Is Loaded.
Step Remedy
1 The tension spring is dislocated form the lifter driving gear (a
crescent gear). Therefore, mount it properly.
